Question

我正在使用此preg_split来分割法线，只要后面有空格或大写字母的点都可以。

$p = "This is a dummy text. And it has a new line in it \n it also has dots. Byt not";
$arr  = preg_split('/\.\s*?(?=[A-Z])/', $p);

这也可以防止段落中的最后一个点被分割（这是我想要的），但是，我现在也需要它来分割新行（或行）。我无法把头缠住...：（

Answer 1

尝试一下：

$arr  = preg_split('/\.\s*?(?=[A-Z])|(\r\n|\n|\r)/', $p);

Answer 2

您可以使用以下一种替换方式来进行拆分：匹配一个点，然后匹配0+个水平空白字符，然后匹配1+个大写字符或| Unicode换行符序列：

\.(?=\h*[A-Z])|\R+

例如：

$p = "This is a dummy text. And it has a new line in it \n it also has dots. Byt not.";
$arr  = preg_split('/\.(?=\h*[A-Z])|\R+/', $p);
